Two-stage reconstruction of post-traumatic segmental tibia bone loss with nailing.
Treatment of lower extremity segmental bone loss is difficult. Masquelet et al. proposed a two-stage technique: first, debridement and filling of bone loss with an acrylic spacer; second, bone reconstruction by filling with cancellous bone in the space left free (following cement removal) inside the so-called self-induced periosteal membrane. In the originally described technique, the fracture site is stabilized by an external fixator, which remains in place throughout the bone healing process, i.e., often longer than 9 months with all the known disadvantages of this type of assembly. Following the principle of two-stage reconstruction, we modified the technique by reconstructing around an intramedullary-locking nail placed in the first stage. ⋯ Level IV. Retrospective study.

Comparative StudyFifth metacarpal neck fracture fixation: Locking plate versus K-wire?
Neck fractures of the fifth metacarpal bone can leave sequelae. Surgery is indicated when the displacement of the head in flexion exceeds 45° and/or rotation is impaired. Among available techniques, non-locking mini-plates have the most drawbacks; recently developed locking plates may, however, challenge the preference for K-wires. ⋯ Level IV continuous prospective comparative study.

Computer-assisted total knee arthroplasty: Does the tibial component remain at malposition risk?
The development of computer-assisted surgery in total knee arthroplasty continues its search for better accuracy in the spatial positioning of prosthetic components and in achieving the best ideal ligament balance. Many studies have underscored the value of computer-assisted navigation in obtaining precise bone cuts in terms of both orientation and location, which would optimize bone resection and thereby fulfill ligament balancing requirements. Yet improving bone cut accuracy can be undermined by positioning errors of the component at the final stage of implantation. The objective of this prospective study was to assess this possible loss of accuracy and to suggest possible solutions to minimize this risk. ⋯ Level IV. Prospective study.
